I need to buy a couple of 10 speed cassettes so I've been looking around online as campy stuff is difficult to obtain where I live.

Here's the ratios I could find in centaur & chorus:
11-12-13-14-15-16-17-19-21-23
12-13-14-15-16-17-19-21-23-25
13-14-15-16-17-18-19-21-23-26
13-14-15-16-17-19-21-23-26-29

They're basically the same for veloce except they do a 12-23 without the 11 cog. I don't need or want record cassettes & I don't like the quality of Miche cassettes (I've seen the teeth break).

Now keep in mind I live in an extremely hilly area... the third largest volcano in the world... you're either cycling up or you're cycling down. There's almost no inbetween, except when cresting a hill. So I'm either at the top end of the cassette or the bottom.

I have a few different needs for the 2 cassettes.
One of the cassettes is for myself and so a 12-25 will suffice. I'll be running a compact 34/50 crank with 700c wheels on one bike & a standard 39/53 crank with the other 650c bike. So a 12-25 is usually ideal. I've got a 12-23 now and find myself struggling up steep grades... so I have to avoid those for the time being cause I don't want another knee injury...

Anway, the other cassette is for a rental bike. With a standard 39/53 crank, many people find the 12-25 too tough. Give them a triple for example and they'll often use the lowest gear of all the whole way up a climb. That's why most of my rental bikes have triples. I like to give people the option of a double, but I'm not investing in tonnes and tonnes of bikes just for them to go unused. So during the peak season, I have to make do with what I have and the levers aren't triple compatible. If I run a 13-26 or 13-29, and/or install a compact crank, I imagine they'll run out of high gears on the way down. :x

I'm wondering a few things:

Why isn't there a 12-28 or something similar to shimano?

If I want a cassette with a cog larger than 25, why do I have to sacrifice the 12T ? :(
Why they don't do an 11-21 in anything but record? (not that I could use it here, but if I lived in holland I'd be pretty pissed... you can buy 11-21 in ultegra which is pretty cheap)

Also on the subject of Campagnolo cassettes, I notice the new 11 speed super & std. record cassettes are selling for between $384.95 - $479.95 at excelsports. How many think that's overpriced for a consumable item? :shock: (just to clarify, I'm not pointing the blame with retailers)

I think Marchisio can do a 12-28 cassette for Campag. I had a conversion cassette with a 12/28 Shimano, it was OK, but not great.

Thanks for the suggestion... I've tried marchisio cassettes before too (a straight block 12-21 :twisted: ) and wasn't impressed with the shifting performance. Teeth are just twisted on them, no proper ramping patterns.

I think I might spring for a 13-29 and see how that goes. According to my calcs, I think they should still be able to hit around 60-65kph @ 120rpm.

I use 13/29 and 34/50 as I'm an old git. I'm with Madcow on cassettes, best buy proprietary.

The other alternative would be to run 12/27 Shimano with a Shiftmate, but I know they're not everyone's cup of tea.

You can still get going fairly fast with a 53x13..... above 40mph. If you are going faster than that... and are going downhill, you're better off tucking in anyhow.

Campy forgoes the 12T so you don't get nasty gaps in the gearing. A 13-26 also give you the 18T cog.

If you want inexpensive Campy cassettes you are looking at the wrong place at excel! Probikekit has Centaur cassettes for $58, with free shipping. That's pretty amazing. THey also have Record cassettes for about $180 USD.

Check Totalcycling.com for good prices on the 11speed stuff.

In a sprint a 53-12 will take you up to 60kph...barely

In the saddle the same ratio will take you up to 65kph

Last thing you want to be worrying about is your customers running out of gears downhill. Doing 1kph extra downhill makes fa difference to their ride time. An extra kph uphill makes all the difference.

My vote is for 34x25 or 28 compact. Triple is OK, but I find feels cowboy like.

P.S. I stayed in the parador at the top of Teide 2 yrs ago, but didn't bike. I was quite glad as it looked bloody hard work. Literally no flat, intermittently very poor road surfaces, switchbacks, very steep bits. Good if you're fit. Make you want to quit if you're not.

Yep I agree... adequate gearing for the uphill stints takes priority.

Tell me about it. I had a big break from road biking this year after a iliotibial knee injury. It's taken me 6 weeks of training just to be able to do a 75km ride comfortably! :oops: I'm finally about to tackle Mt Teide this week [possibly tomorrow]. Went up slowly yesterday but got stopped half way by the shit weather. This is where the pros come to train! :twisted:

For those that don't know, you can ride from sea level to 2300m in about 40km.

Riding in Colorado mountains, I chose a 53/39/28 triple with a 12-25 for the previous 4 years, but switched to a 50/34 with an 11-25 this year. So far, the compact has proven adequate and the lack of the 16T is not a big deal with the 50/34. The problem for weaker riders, is you're losing two of the lowest gears, compared to the triple.

All Campy shifters are triple compatible, so that should never be an issue with a Campy drivetrain.

If you've got bikes with a 53/39 for rental, a 13-29 would be a good choice for climbing, but you really should have a medium cage RD with that setup. You can barely get by with a short cage, if the bike just happens to have the perfect chainstay length, but some will overextend the RD if it's ever shifted to the 53/29. Adding 1 inch of chain can result in the chain hanging loose in the 39/13.

I don't get the complaint about the prices for 11 speed parts at Excel. All US dealers are charging MSRP for 2009 parts, at present. No one in their right mind would buy from US sellers right now.

If you want good prices, buy from a European source. Comobike has Centaur 10 cassettes in all ratios for 79 AUD. Chorus 11 speed cassettes will be 163 AUD (111 USD) when they get some stock. That's cheaper than the average price for 2008 10 speed cassettes at most US sources.

OK.
1. By two Veloce cassettes and make whatever you want, 11-29.
2. In US retail, "Early adopter" = sucker
3. the best thing about the $480 cassettes is that they will last half as long as the $50 cassettes.
4. See 2.

Honestly, if Campy announced Super-Duper Record at $6,000, everyone would bitch about the price, yet some would still buy it.

I suspect most renters will be just fine with the 50/13 on descents. How many of them pedal much on the downhills anyway? If they're touring, they want to enjoy the views. I was in Tuscany last year and couldn't be bothered to put a 12-29 together (see below) so I lived with the 13 as my big gear with a compact and I still enjoyed myself.

For what it's worth, if you have some old cassettes lying around, you can make a 12-29 by using the 12-15 from a 12-23 or 12-25 and the 17-29 from a 13-29. I've done it a couple of times and it works fairly well. The worst shift on my bike was not the 15-17 but the 17-19, even though it was from the same original cassette.

I agree that a 12-29 or 12-28 would be nice to have. Even with 11 speed, Campy has decided to give us the 12-27 for fondo riders. At 57 and counting, I'd like something lower for the big hills in Europe, although a 25 is still fine around here.

Unless you're young and racing the 13/29 is a good option as it gets you over just about anything and as Jim said the 50/13 is also fine and should suit all but the very fittest.
